inFigs. 7 and 8 of the'drnwings. This'fl valve 16 is mounted folrotating on the pis-"j ton 6, the valve 16 being sevured 0111 stud 17,which is join-milled in a bearing lSfi'nflj the "piston 7. To thisstilil 1 there-isse f! eu'redn ratchet wheel 19,,whieh is engugbil iby 1. pawl 20, pi\"oted tothe under side of the piston, and heldin.operativeposition There is also secured to this sti d jl'Tn'I-beele(1 ge:i'1' ,wl1eel 22, with which meshes v bevel'ed" gear wheel 23,nonntml looselyen :1 pin .24 'mountedin the piston.

.Fig. 2 of the drawings shows the position of the valve at the firingstroke. Fig. 7 shows the position of thevalve at the'end of the firingstroke, andthe' commencement of the scavenger stroke. Fig. 8 shows theposition of the valve at the end if the scavenger stroke and thecommencement of the inlet stroke, and Fig. 9 shows the position of thevalve at the commencement of the compression stroke. r

-It will be seen that the'valve 16- makes a one-quarter revolution witheach coui-, plete rotation of the shaft 34, which is con nected with thepiston rod 25, by means of the crank 35. This rotary movement of thepiston 16 is obtained by means of the relative sizes of the beveled gearwheels 22 and 23. The'piston rod'25 on the firing stroke shown in Fig. 2of thedrawings rotates, by the means described, the beveled gear 23,sufiiciently far for this beveled gear 23 through the beveled gear 22,to rotate the stud 17, a distance sufficient to move the valve to theposition shown in Fig. 7, at

which point the scavenger ports 33 in the valves 116 are incommunication with the scavenger ports 7 and 8 in the pistons 6, thesescavenger ports 7 and Sbeing elongated as'shown' in Figs. 7, 8 and 9 ofthe drawings. \Vith the pward movement of the piston 6 the dale 316 55moved by the means described to the position shown in Fig. 8 0f thedra\vings',and with the downward or inlet stroke'of the engine, thevalve 16 is moved from the position shown-in Fig. 8 of the drawings tothis position shown in Fig. 9 of the drawings, at which point one .ofthe inlet ports 32- has been brought into engagement with the inlet portvalve 30, permitting the explosive mixture to fiow therethrough, andinto the cylinder, so that with the upwardmovement of the piston 0n thecompression stroke the combustible mixture will be compressed to befired in a manner readily understood. 1

In the two-cycle typeof engine, shown in Fig. 10 of the drawings, thepistorl 36 corresponds with the piston 6 shown in Fig.

1 of the drawings, and the inlet port 37 in the cylinder. the scavengerports 38 and 39 in the cylinder and the scavenger ports 40 and in thepiston eorrespondirig wit the simila inlet and ports shown in Fig. ,of,the drawings. The valve 45 has a rim 42, with a valve port, 45'.Thetwq-cycle ena'stud 43, which is jo r aled in the bear-- ing 44, inthe piston 36, t e valYe 45 being secured to the upper end 'of the stud43 and a beveled gear wheel 46 being secured to the lower end of thestud 43. This beveled gear wheel 46 is in mesh with a beveled ear wheel47 secured for rotating at all times with the upper terminal .48 of thepiston rod 49, which is articulated to the piston 36 in the customarymanner. It will, therefore, be seen that with this construction thevalve 41 will rock with the rotation of the shaft 50, and that it willnot rotate in the gi'ne shown in Fig. 10 otxthe drhi'wings has 'w ,samedirection intermittently, as is the case 45 will rotate to the positionshown in Fig.-

12 of the drawings, when the scavenger ports 51 in the valve 45 will bein communication with the scavenger-ports40 and .41 III the piston 36",to permit a blast of air to flow through the ports 38, the port 40, oneof the ports 5.1, through the cylinder to the port 51, through a. port41, andv out ofthe ports 39. vThis will carry the "alve 45 as far asitwill travel in one direction, and with the movement of the valve in theopposite direction it will be pawed to the po sition shown in Fig. 13 ofthe drawings, at which point the piston is at its lowermost position, topermit the admission of an explosive mixture through the port 37, andthe valve port 45,-the valve 45 continuing to rotate in thelast-mentioneddirection with the upward movement of the piston and withthe compression of the combustible mixture so that when the piston hasmoved to its uppermost position the-ports 51 in the valve 45 willdisposed as shown in Fig.- 11 of the drawings at which point theexplosive mixture will be fired.
